Umreo STATES ELIE MONEUSE, OF NEW YORK, N. Y.

FlRE-GRATE.

SPECIFICATION forming part of Letters Patent No. 228,376, dated June 1,1880.

Application filed March 24, 1880. (No model.)

To all whom it may concern Be it known that I, ELIE MoNEUsE, of thecity, county, and State of New York, have invented a new and usefulImprovement in Fire- Grates, which invention is fully set forth in thefollowing speci fication, reference being had to the accompanyingdrawings, in which- Figure 1 represents a front view of my grate appliedto a furnace. Fig. 2 is a vertical crosssection thereof. Fig. 3 is avertical longitudinal section of the same.

Similar letters indicate corresponding parts.

My invention is adapted to grates for any useful purpose; and itconsists in the combination of a revolving grate having a segmental orsemicircular cross section and a latch for retaining the grate in itsnormal position, so that the grate may be dumped and returned to anupper or normal position without difficulty. The latch allows the grateto be oscillated or shaken on its axis, and, moreover, is self-acting,the latch being arranged to engage a radial arm projecting from thegrate-shaft, and having two beveled ears, between which the radial armis permitted to move, and which allow such arm to take its place betweenthem when the grate is moved to an upper position.

In the drawings, the letter A designates a portion of a furnace orstove, forming bearings for the shaft B of the grate G. The shaft Bprojects through the front of the stove, and is squared at the outer endto receive a key for revolving the grate.

In cross-section the grate 0 forms a segment of a circle, and it ispreferably made semicircular, as shown in Fig. 2. In its normal positionthe grate 0 stands above its axis and presents a convex surface to thefire-pot of the stove.

In stoves containing the ordinary flat revolving grate it is necessaryto remove the ashes from the ash-pit, after dumping the same, before thegrate can conveniently be returned to an upper or normal position, andsince the ashes are usually dumped in a burning state it is common toleave the whole untouched, after (lumping, until the ashes cool off. Theresult of this practice is that the grate-bars burn out in a short time.

It will be readily perceived that by the shape of the grate 0 it isadapted to be overturned for the purpose of dumping the ashes andimmediately returned to an upper position.

The letter D designates a lat-ch used for the purpose of retaining thegrate O in its upper or normal positionh This latch is hung on a pivot,c, at one end, and acts on a radial arm, F, projecting from thegrate-shaft B, both the latch and arm being situated on the front of thestove, where the latter is provided with a rest, g, for the free end ofthe latch. On the latch D are two ears, h, which are beveled on theirouter edges, their inner edges being straight.

When the grate G is turned from a lower to an upper position the radialarm F strikes the beveled edge of either of the ears h, according to thedirection of rotation of the grate, and by this means the latch israised, so that the radial arm may take its place between the two cars.The space between the ears It allows a movement of the radial arm F, andit follows that the grate C may be oscillated or shaken on its axis.

The letter I designates the bars of the grate C. These bars are mountedon the shaft B, and held or fastened together by a tie-rod,j, passingthrough lugs projecting inwardly from the bars. By this arrangement thebars I are rendered removable, and may be respectively replaced, whenburned out, by a new bar.

On one side of the bars I are spurs I, while on the opposite sidethereof are sockets which correspond to and register with the spurs, sothat when the bars are put together such spurs and sockets interlockwith each other.

In this manner the bars I are held against longitudinal displacement,and the joint between them is improved.

In this example the bars I are independent of each other throughout thegrate; but, if desired, the bars intermediate of the two end bars may becast all in one piece. Said two end bars are fastened to thegrate-shaft'by pins m.

What I claim as new, and desire to secure by Letters Patent, is-
